During the last years, different methods for identifying permanent magnet synchronous motor (PMSM) parameters have been developed. Such allow a better characterization of PMSMs, thus enabling control. This article presents novel PMSM parameter estimation method based on differential power factor due to harmonic distortion, which allows identification from data acquisitions representing entire t...

The effectiveness of a permanent magnet synchronous motor (PMSM) drive managed by an automatic voltage regulator (AVR) microcontroller using field oriented control (FOC) with space vector modulation (SVM) and diode clamped multilevel inverter (DCMLI) is investigated. Due to its efficacy, FOC would be widely implemented for PMSM speed regulation. primary drawbacks 3-phase classic bridge appear r...

A Caputo-type fractional-order mathematical model for "metapopulation cholera transmission" was recently proposed in [Chaos Solitons Fractals 117 (2018), 37--49]. sensitivity analysis of that is done here to show the accuracy relevance parameter estimation. Then, a fractional optimal control (FOC) problem formulated and numerically solved. cost-effectiveness performed assess studied measures. M...

Electric vehicles are regarded as a significant way to mitigate the global energy crisis and environmental pollution problem. Motor control is very important part for electric vehicles. As hardware, motor controller usually has components such power module, microprocessor unit, IGBT driver, sensors, resolver-to-digital convertor. software, field-oriented (FOC) with space vector pulse width modu...

Issue Fear of childbirth (FOC) can be debilitating, impacting women's lives in pregnancy, the puerperium and beyond. Research investigated various interventions for FOC perinatal period, but there been no synthesis experiences women who engaged with these interventions, which would inform clinical practice guidance development future interventions. Aim To conduct a review qualitative stu...

Development of resistant cultivars for Fusarium basal rot (FBR), a fungal disease caused by the soil-borne fungus oxysporum f.sp. cepae (FOC), is major breeding goal onion programs around world. Currently, selection FBR-resistant bulbs based on visual interval or category scale, which an entirely subjective method. This study aimed to develop objective approach using digital image analysis quan...

Endothelin-1 (ET-1) has acute positive inotropic effects, but consequences of chronically increased ET-1 on contractile function of cardiac myocytes are largely unknown. In the present study, effects of long-term treatment with ET-1 (10 nM) for 5 days on both force development [force of contraction (FOC)] and kinetics of contraction were determined in heart tissue reconstituted from rat cardiac...

Wilt caused by Fusarium oxysporum, sp. Ciceris (FOC) is an important disease causing losses up to 10% in chickpea yield. Experiments were conducted growing free air ozone and carbon dioxide enrichment rings under four treatments of elevated (O3) (EO:60 ± 10 ppb), (CO2) (ECO2:550 25 ppm), combination CO2 O3 (EO + ECO2) ambient control for quantifying the effect on growth, yield, biochemical nutr...
